Thermocouple Type K M6

As a temperature sensor, thermocouple type k m6 are usually used in conjunction with display instruments, recording instruments, and electronic regulators. Generally used to measure the temperature of heated metal solids. K-type thermocouples have advantages such as good linearity, large thermoelectric electromotive force, high sensitivity, good stability and uniformity, strong oxidation resistance, and low cost.

① Stainless steel braided/silicone, 7-core/0.2 stranded wire core.

② High-temperature antioxidant hot end heat transfer tube. Copper material, good thermal conductivity, high temperature resistance and oxidation resistance.

③ High resistance bending protection spring, made of stainless steel material

④ Thermocouple wire accuracy: General industrial grade Level II

⑤ Graduation number: K

⑥ Range: 0-250 ℃

⑦ Easy to assemble, the hot end is fixed on the tested object, and the SV terminals are connected to the display instrument+and - terminals in red and blue respectively.

(1) The thermocouple performance is stable within the temperature measurement range and does not change with time and the object being measured;

(2) Stable physical and chemical properties within the temperature measurement range, resistant to oxidation and corrosion, and radiation resistance;

(3) The thermocouple should have sufficient sensitivity and the rate of change of thermoelectric potential with temperature should be large enough;

(4) The thermoelectric characteristics are close to single value linear or approximate linear;

(5) High conductivity, low temperature coefficient of resistance;

(6) Good mechanical performance, high mechanical strength, and uniform material; Good craftsmanship, easy processing, good reproducibility, simple manufacturing process, and with affordable price.

Proper installation and wiring are essential to ensure the accuracy and service life of the Thermocouple Type K M6. Follow these practical guidelines for optimal performance:

• Mounting: Use the M6 thread to fix the sensor firmly to the measured object (such as metal surfaces, pipes, or equipment walls). Ensure the thread engagement is tight to avoid gaps that could affect heat transfer and measurement accuracy.
• Wiring: Connect the red SV terminal to the positive (+) terminal of the display instrument and the blue SV terminal to the negative (-) terminal. Avoid reversing the connection, as this will cause measurement errors.
• Wire Handling: Avoid excessive bending or pulling of the lead wire, especially at the connection with the sensor body. For stainless steel braided wire models, avoid sharp bends that could damage the braided layer; for silicone wire models, keep the wire away from high-temperature areas exceeding 200℃.
• Installation Position: Install the sensor in an area where it can fully contact the measured object, avoiding direct exposure to open flames, excessive airflow, or corrosive media. For pipe temperature measurement, ensure the hot end is in full contact with the pipe surface to ensure accurate heat transfer.
• Protection: Keep the sensor's hot end clean and free from dirt, oil, or debris, which can reduce thermal conductivity and affect measurement accuracy. Regularly inspect the protection spring and wire for damage, and replace the sensor if necessary.
